Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661476, here are decompositions:

7 + 8661469 = 8661476
37 + 8661439 = 8661476
223 + 8661253 = 8661476
283 + 8661193 = 8661476
433 + 8661043 = 8661476
547 + 8660929 = 8661476
613 + 8660863 = 8661476
709 + 8660767 = 8661476

Showing the first eight; more decompositions exist.
